Intrusion management system and method for providing dynamically scaled confidence level of attack detection

An Intrusion Management System detects computer attacks and automatically adjusts confidence that an attack was correctly detected. When the Intrusion Management System detects the attack against a computer system, it does not represent an accuracy of detection as an immutable confidence value. Instead, the Intrusion Management System tabulates information indirectly related to the attack and dynamically scales the confidence in the attack detection accordingly.
